摘要
从惠更斯一菲涅耳原理出发,在菲涅耳近似和夫琅和费近似的条件下,全面讨论了矩形孔径对会聚和准直高斯光束的对称和非对称一维切割的各种衍射效应,得出有实用价值的结论。
Using Huygens-Fresnel principle,the diffraction effects of the symmetrical andthe asymmerical one-dimentional truncation for the converging and the collimating Gaussianbeam through rectangular aperture are discussed entirely under the Fresnel and the Fraunhoferapproximate conditions.The practical conclusions are obtained in this paper.
